So in a previous post I pointed out that Tiers XI, XII, and XIII (11, 12, and 13) have exactly the same rewards except for a small increase in shards but have increasing difficulty and damage thresholds. Tier XIV however did have increased rates for items including the introduction of Eveline Crystals to the loot table. Sadly however, we come to find out that Tier XV has exactly the same loot table as Tier XIV (with a small increase to possible shards; 70 instead of 65) and again with much higher difficulty and increased damage thresholds:
Disappointing.
